F5 Networks BIG-IP : Linux kernel vulnerability (K51674118)

high Nessus Plugin ID 150465

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 13.1.4.1 / 14.1.4.3 / 15.1.4 / 16.0.1.2 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K51674118 advisory.

The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)ImpactA locally authenticated attacker can discover sensitive information, cause a denial of service (DoS), or impact the system in another way by triggering a race condition with the vulnerable component.

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K51674118.
